Hi Terry - don't think debounce is the issue. Don't want to get too bogged down in this - it's something I've noticed and thought I'd mention. It's NOT really a problem I think if your accel/deccel is decent. Anyway FWIW...

See attached pic.

It's meant to represent a downward probe (i.e. in Z). In both cases the probe trips on the step and then decelerates and comes to a  halt at the position shown (obviously exagerated). In the RIGHT hand case all works as you'd expect. The stored point is where it hit the step. However in the LEFT hand case the recorded point is where the probe stops and NOT where it tripped.

HI Ian Good to hear from you(;-)  I was about to email you to check on you.

I agree on not getting bogged down on the subject BUT it is something that Brian needs to check out as it should NOT do that.

Maybe Andrew can check it out for Brian to test.

(;-) TP

Hi all.

I now have made the probe and installed it to my mill and everything works well.
Attach a picture of the probe and the wiring diagram I have used.

Thanks for nice words.
No the tip is madi in my lathe of silversteel, but the ball is a 3mm ball from a ballbearing. It is first softened, glued to a holder and a hole 1,7 mm was made. Then it was hardened and glued to the shaft.
